Well... there is a YA fantasy book that had something to do with elves in my country's folklore
And then I saw that in the sleeve or what you call it, it explained about those elves was and then "source: Wikipedia"... lol
They seriously used Wikipedia as a source.
I would have found it understandable, if it was written like 15 years ago when people found that website more reliable (or I'm not sure when people started to find it less reliable), but this book was released few years ago...
